Application filed April 3, 1911. Serial No. 618,695.

To all whom it may concern:

Be'it known that I, l/VILLIAM B. Coccnn, a citizen of the United Statesof America, residing at Cleveland, in the county of Cuyahoga and Stateof Ohio, have invented certain new and useful Improvements in Standardsfor School-Desks or other Objects; and I hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and usethe same.

This invention relates to improvements in standards for school-desks orother objects, and pertains more especially to a standard of thecharacter indicated which comprises a base provided with an upwardlyprojecting tubular stem which surrounds a stem adapted to bear adesk-proper or other object and depends into and is adjustable up anddown the first-mentioned stem and suitably secured in the desiredadjustment, which adjustable stem is not only provided with two slotswhich are arranged at opposite sides respectively of the adjustable stemand extend laterally from the interior to the exterior and endwise ofthe stem but divided between its slots into two upright sections andprovided internally of one of the said sections between the jointbetween the said sections and one of the said slots with teeth which arespaced endwise of the adjustable stem and form a rack which is arrangedinternally of the adjustable stem and in mesh with a pinion mounted onand operatively connected with a horizontally arranged shaft whichextends through the adjustable stem at the slots in the stem and hasbearing in the relatively stationary stem of the base.

The primary object of this invention is to provide a standard of thecharacter indicated whose component parts are readily assembled, andwhich is exceedingly simple and durable in construction.

With this object in View, and to the end of attaining any otheradvantage hereinafter appearing, this invention consists in certainfeatures of construction, and combinations and arrangement of parts,hereinafter described, pointed out in the claims, and illustrated in theaccompanying drawings.

In the said drawings, Figure 1 is a side elevation of a school-deskcomprising a standard embodying my invention. Fig. 2

is a vertical section on line 22, Fig. 1 looking in the directionindicated by the arrow. Figs. 3, 4, and 5 are horizontalsections onlines 33, 44 and 55, respectively, Fig. 2, looking downwardly. Fig. 6 isa vertical section on line 66, Fig. 2, looking in the directionindicated by the arrow. Fig. 7 is a vertical section on line 77, Fig. 2,looking outwardly. Portions are broken away in Figs. 1, 2, 8, 4, and 5to reduce the size of the figures.

My improved standard comprises a base A adapted to be secured to a floornot shown. The said base is provided centrally with a verticallyupwardly projecting tubular stem at which is cylindrical incross-section and provided interiorly of its upper portion with twovertically spaced annular projections 10 and 10 which project later.ally and inwardly.

A vertically adjustable stem 6, which is adapted to bear a desk-proper Bor other object at the upper end of the stem, depends into therelatively stationary stem a. The stem 6 is adjustable therefore up anddown the stem 64 and secured in the desired adjustment as willhereinafter appear. The stem 6 is approximately cylindrical incrosssection and provided with two vertically arranged slots 12 and 12which are arranged at opposite sides respectively of the stern andextend endwise or longitudinally of the stem and laterally from theinterior to the exterior of the stem. The slotted portion of the stem 1)extends a suitable distance into the stem a.

The adjustable stem 6 is provided exteriorly with fiat surfaces 13 whichextend up and down the said stem at the sides of and above and below theslots 12, and consequently extend longitudinally or endwise of the saidstem, and obviously the provision of the flat surfaces 13 preventcontact with the projections 10 by the said stem next the said slots.

The stem 6 is divided vertically and centrally between its slots 12 and12, as at as, into two vertically arranged or upright sec tions 14 and14. The stem 6 is provided internally of one of itssaid sections betweenthe joint between the sections and one of the slots 12 with teeth 15which are spaced vertically or endwise of the said stem and form avertically arranged rack internally of the stem.

A horizontally arranged shaft D extends through the adjustable stem I)at and through the slots 12 in the said stem and has bearing in therelatively stationary stem a centrally between the projections 10 and 10of the last-mentioned stem. The shaft D is provided at one end thereofwith a laterally and inwardly facing shoulder 16 arranged to bearagainst the adjacent flat surface or surfaces 13 of 'the adjustablestem, and has its opposite end extending externally of the stem (4 ofthe base A. The shaft D is provided with a groove (Z extending from theshoulder 10 at one end of the shaft to the opposite extremity of theshaft, and a nut C is screwed onto the shaft at the lastmentionedextremity of the shaft and spaced from the stem (4 of the base A. A,collar E is loosely mounted on the shaft D between the nut C and thestem a of the base A and provided internally with an inwardly projectingtongueor member a engaging the groove (Z. A pinion G is mounted on theshaft between the slots 12 and 12 in the stem Z), which pinion mesheswith the rack formed by the teeth 15 and is provided internally with aninwardly projecting tongue or member g engaging the groove (Z in theshaft. It will be observed therefore that the pinion G and the collar Eare operatively connected with the shaft, and the said collar is looserelative to the stem a of the base A when the nut C is loose relative tothe said collar, and the said collar is employed as a wheel or memberwhich, when it is loose between the said stem and the nut, may berotated in any approved manner to rotate the shaft and thereby adj ustthe st m 6 vertically and thereby vertically adjust the desk-proper orobj ect 13 mounted on the upper end of the said stem. Upon manipulatingthe nut G to cause it to clamp the collar E against the stem (4 of thebase A the shaft is shifted endwise in the direction required to causeits shoulder 16 to clamp the flat surface or surfaces 13 formed on theadjacent side of the adjustable stem Z) and thereby clamp the latteradjacent the flat surface or surfaces 13 formed on the other side of theadjustable stem against the projections 10 and 10 of the relativelystationary stem a. It will be observed therefore that the adjustablestem Z) and any object carried thereby are not only secured in thedesired vertical adjustment by manipulating the nut as required to clampthe collar against the stem a. of the base A, but the adjustable stem isclamped against each projection 10 of the relatively stationary stem attwo points spaced circumferentially of the rack'bearing section of theadjustable stem. I would also remark that the pinion G is provided atone end thereof with an annular circumferential surface 17 and a pin ormember 18, which is borne by one of the sections of the adjustable stemZ) below the slot in the respective stem-section, is arranged or extendsunder and affords hearing to the said annular surface.

The stem (4 is of course provided with two holes 20 and 20 which areformed at opposite sides respectively of the stem a of the base A andare arranged in line endwise and extend from the interior to theexterior of the said stem, which holes are arranged to receive the shaftand. are large enough diametrically to accommodate the rotation of theshaft which has hearing at the surrounding walls of the said holes inthe stem at of the base A. In assembling the parts therefore the pinionis placed on the pin or member 18 of the adjustaliile stem Z) and inmesh with the rack formed on and internally of the said stem before thelatter is applied to the relatively stationary stem (4, whereupon thepinion-bearing adjustable stem 6 is lowered into the relativelystationary stem a far enough to bring the lower end portions of theslots in the adjustable stem into registry with. the shaft-receivingholes 20 in the relatively stationary stem, and thereupon the shaft isinserted endwise into the said stems at the said holes and slots and soplaced that its groove will re ceive the tongue or inwardly projectingmember 9 of the pinion, whereupon the collar E is placed in position toenable its tongue or inwardly projecting member 6 to enter the saidgroove and thereupon the collar is slid into place on the shaft,whereupon the nut is applied, ano after the collar has been rotated torotate the shaft and thereby place the adjustable stem Z) in the desiredadjustment the nut is tightened to effect the clamping of the adjustable stem to the relatively stationary stem (1.
